CLEMENS OPPENHEIMER, OF STRASSBURG, GERMANY.

FLEXIBLE ROLL FOR LEATHER-SPLITTING MACHINES.

Specification of Letters Patent.

Patented June 6, 1916.

Application filed October 1, 1915. Serial No. 53,633.

To all whom it may concern: 7

Be it known that I, CLEMENS OPPEN- HEIMER, a subject of the Emperor of Germany, residing at Strassburg, in Alsace Lorraine, Germany, have invented certain new and useful Improvements in Flexible Rolls for Leather-Splitting Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to a flexible roll for leather splitting machines consisting of a number of movable parts as, for instance, balls and globularlyv grooved cylinders, the former lying in the grooves of the latter. The flexible roll can therefore slacken under pressure without forming projecting edges which would cause the splitting tool to damage the leather. The parts of the roll keep their relative positions under all circumstances.

In the drawing: Figure 1 is a side View of a leather splitting machine according to the present invention. Fig. 2 is a longitudinal section through the flexible roll. Fig. 8 is a front view of the same. Fig. 4. is a similar view of the flexible roll, slackened.

The leather (1 which is to be split by the splitter i rests between a roller 6 and a roller 0 which engages a wall d and a rubber roller 6. The roller 0 consists of cylindrical parts f provided with globular hollows or grooves in which balls h are resting, the surfaces of which are flush with the surface of the grooved cylinders, as cylinders and balls have the same diameters. If the roller 0 is pushed in by inequalities in the leather projecting edges causing the splitting tool 2' to damage the leather, will not be formed as the light movability of the flexible roll or its parts will efliciently prevent the formation of such edges.

That I claim is In a flexible roll for leather splitting machines in combination, grooved cylinders and balls in the grooves of said cylinders, said balls and cylinders having equal diameters, substantially as described and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

CLEMENS OPPENHEIMER.
